LATCH BOLT.

Application filed April 16, 1925.

This invention relates in general to imgu-orements in latch mechanisms,

It is the principal object of the invention to provide a latchconstruction which can be economically constructed and installed andwhich will operate in an efficient mannerwhen so installed.

It is a more specific object to provide a latch member which can bestamped from sheet r aterial if desired with the resultant economy oftime without in any manner sacrificing the usefulness of the completedconstruction.

Other and more specific objects will appear from the followingdescription considered in connection with the drawings in which:

Fig. 1 is a horizontal section through a portion of an automobile doorshowing our invention applied thereto the section being takensubstantially on the line 1-1 of F 2.

Fig. 2 is an elevational view thereof.

Fig. 3 is a section similar to Fig. 1 showinp; the latch member inlatching position.

Fig. 4; is a perspective view of the operating latch member.

Referring to the details of the drawings there is shown certain portionsof an automobile frame member 5 having an opening 6 therein. The framemember 5 may be a portion of an automobile door having the side member 7constituting the abutment portion thereof at the free or swinging edgeof the door. It is to be understood that the frame part 5 may be anysuitable supporting frame member to which we may apply the latchmechanism hereinafter described.

The latch member indicated generally at 8 includes the base portion 9and the latching extension 10 arranged at an angle to the base portion.The angular extension preferably has a slightly reduced width relativelyto the base portion 9 of the latch in order to form the shoulderedportions 11 thereon which operate .to space the latch member withrespect to the frame member 5. The angular extension 10 of the latchmember has an inner end or base portion 10 of substantially the sameproportions as the opening 6 in the frame. The extension 10 is arrangedto be passed loosely through the opening 6 in the frame 7 and Serial No.23,814.

is limited from outward movement therein by the shoulders 11 and fromrearward movement by reason of the angular arrangement of saidextension.

The control for the latch comprises a spring member 12 which may bemounted between the base portion 9 of the latch and the frame part 5 andsecured in position with. respect to one of these members. The operatortherefor includes the transverse operating shaft 1 L connected to thehandle member (not shown) in the usual mannei; the shaft 14- havingrigidly mounted thereon the outwardly extending arm 15 arranged toslidably engage against the face of the latch member so as to move theparts to un latched position as shown for example in Fig. 1. The shaft14 and arm 15 are held in inoperative position or in position to permitthe latch member 8 to function by any desired spring arrangement thatshown comprising the engaging spring 16 supported by the frame as at 17and engaging against the free end of arm 15 to move the same to thedotted line position shown in Fig. 2. The springs 12 and 16 operate inconjunction to cause the latch mechanism to function automatically butpermit manual control thereof for unlocking the same.

It will be seen that according to the above described construction thelatch member 8 is formed as an angular plate which may be quickly andeasily stamped from a plate of sheet metal. The assembling of the latchis likewise facilitated since before the operating arm 15 is installedin position the latching extension 10 can be passed through the opening6 so as to bring the shoulders 11 against the edge of said open ing. Theoperating arm is then mounted in position shown for example in Fig. 3and the latch is ready for use. It is prevented from sliding outwardlythrough the opening by means of the shoulders 11. and from sliding backinto the frame member by reason of the angular arrangement of theextension 10. The latch member so constructed is readily displaced forautomatic action thereof as when the door is merely pushed shut. Thetension of. the spring 152 is easily overcome by rotation of tieoperating shaft 14- and the consequent sliding of the free end of thearm 15 along the face of the base portion of the latch. lVhen thecontrolling handle is released the springs 12 and 16 return the handleand latch to latching position as shown in Fig. 3.

While we have .shown and described herein a certain specificconstruction it is to be understood that this is merely illustrative andthat the spirit and scope of our invention is set forth in the appendedclaims.

We claim as our invention:

1. In combination with a frame parthaving an opening therethrough, alatch member comprising a supporting base and a locking extension, saidextension passing freely through said opening and adapted to pivot onsaid frame part adjacent said opening, and means movably engaging saidbase for controlling said latch member.

2. In combination with a housing having an opening there-through, alatch member comprising a base and a locking extension, said extensionpassing freely through said opening and adapted to pivot on said housingadjacent said opening, a limiting shoul der formed on said base normallyengaging said housing adjacent said opening to prevent the same frompassing through said opening, and means for controlling said latchmember.

8. In combination with a frame parta latch member comprising asupporting base and an angular locking extension, said latch memberengaging and being pivotally sup ported by said frame part adjacent thejunction of said base and said angular extension, and means to controlsaid latch member.

at. In combination with a frame part having an opening therein, a latchmember rockably supported in said opening and compris ing a plate havinga base portion and an angular extension, the. free end of said GK-tension being movable toward or away from said frame part when saidlatch member is rocked and constituting the latching portion of saidlatch member.

5. In combination with a frame part, a latch member comprising asupporting base portion positioned within said frame. part and anangular'extension positioned without said frame part, said latch memberbeing loosely. supported adjacent the base of said angularextensioi'ifor pivotal movement with respect to said frame part, and manually controlled means operating upon said base portion to control themovements of said latch member.

6. In combination, a frame member pro vided with an opening therein, arelatively flat latch member positioned on said frame member and havinga portion thereof projecting through said opening and supported thereby,the base of said projecting portion being of substantially the sameproportions as said opening to permit the latch member to rock in saidopening but preventing any material bodily movement thereof in saidopening.

7. In combination with a frame part, a latch member rockably supportedthereby said latch member being formed from a single piece of sheetmaterial and including a base portion and an integral extensionangularly arranged with respect to said base portion, a stop elementformed on said base portion, said stop element and the angulararrangement of said extension normally retaining said latch member onsaid frame part, and means to control the movements of said latchmember.

8. In combination with a frame part pro vided with anopening, a latchmember rock-- ably supported by said frame part and coin prising a bodypart and an angularly ar ranged locking extension integral therewith andadapted to extend through said openthe angulararrangement of saidextension forming a shoulder normally engaged with said frame partadjacent said opening for preventing said latch member from movingbodily into said frame part, and means carried by said latch member forpreventing said latch member from moving bodily outwardly through saidopening.

9. In combination with a frame part having a slot therein and anoperating member associated therewith, a latch member comprising anelement projecting out through the slot in said frame part and a basepart lying within said frame, said base part being mounted in positionto be enraged by said operating member, said latch member being rockablysupportedby said frame part for rocking movement ins'aid slot and occupying substantially the entire slot at alltimes.

10. In combination with a frame part, a supporting plate carried therebyand includ ing two angularly arranged surfaces, a latch bolt supportedby said plate and including a part adapted to lie flat against one ofsaid surfaces when in non-latching position and to be'moved outwardlytherefrom into latching position.

11. In a latch mechanism, mounting plate having a narrow slottherethrough, a

bolt loosely passing through said slot and supported therein for pivotalmovement about an axis extending lengthwise of said slot, said slotbeing relatively narrow compared with the length of the projecting faceof said latch permitting said bolt to pivot in said slot from or towardsaid plate into latching or unlatching position respectively.
